Unable to removed shared briefcase

Hello,

I was trying out the new Zimbra briefcase and I ran into an issue when I tried to remove the test briefcase.

If I accept the shared briefcase by clicking the "accept" button in the e-mail message, all is good. If I right-click my briefcase and then choose "link to shared",
I am able to access the brief case, but when I try to right-click/delete it, I do not get any menus to appear so that I can remove it.
